CPR stands for Cardiopulmonary Resuscitation, which is a life-saving technique used in emergencies when someone’s breathing or heartbeat has stopped. This procedure combines chest compressions and artificial ventilation, providing oxygen-rich blood to the brain and other vital organs. The term 'cardiopulmonary' refers to the heart (cardio) and lungs (pulmonary), highlighting the two main components of the body affected during a cardiac arrest.

The other choices do not accurately represent the established definition or purpose of this life-saving technique.
